Three startups to watch from Founder’s Den spring demo day

In a refreshing deviation from the 80 companies that generally present at a Y Combinator demo day, only seven companies (plus two off the record startups) pitched to investors and the media at the Founder’s Den in San Francisco on Tuesday.

“The group, which is a co-working space in San Francisco that allows startups to join and collaborate on an invite-only basis, typically picks startups that have already been through other incubator programs like Y Combinator (which was heavily represented among Tuesday’s startups.) Startups selected to join pay competitive prices for the space and gain access to a well-connected community in the city.”

Survata

Survata finds users to complete market research surveys, integrating with other websites to easily acquire responses. The company explained the idea behind its product on its website: “Our customers write surveys, and we find respondents to complete those surveys. But, unlike most market research firms, we don’t use traditional research panels. Rather, we collect survey responses via our partner publishers around the web.” The company’s founders noted that they’re doing surveys for groups like Disney, Microsoft, Harvard, and McKinsey.

Rollbar

Rollbar works to help developers find and track errors, installing on sites as “a small library to detect errors and collect context about each,” surfacing the most important issues to the developer’s attention, and then working to understand the problem to find a solution. The company has graduated pricing depending on the scale of operation required.
